I can't really help you make better memes...that mostly depends on your sense of humor... Ghostofchurch has a meme stream filled with lots of helpful advice...ask him for a link to it...it will help you a lot.

You could also upvote comments that you reply to...so people will upvote yours...people that don't upvote comments that people make to them tend to get ignored eventually...plus it's just good meme etiquette.
